Changing Patterns of Global Trade outlines the factors underlying important shifts in global trade that have occurred in recent decades. The emergence of global supply chains and their increasing role in trade patterns allowed emerging market economies to boost their inputs in high-technology exports and is associated with increased trade interconnectedness.The analysis points to one important trend taking place over the last decade: the emergence of China as a major systemically important trading hub, reflecting not only the size of trade but also the increase in number of its significant trading partners.
Most trade is invoiced in very few currencies. Despite this, the Mundell-Fleming benchmark and its variants focus on pricing in the producer’s currency or in local currency. We model instead a ‘dominant currency paradigm’ for small open economies characterized by three features: pricing in a dominant currency; pricing complementarities, and imported input use in production. Under this paradigm: (a) the terms-of-trade is stable; (b) dominant currency exchange rate pass-through into export and import prices is high regardless of destination or origin of goods; (c) exchange rate pass-through of non-dominant currencies is small; (d) expenditure switching occurs mostly via imports, driven by the dollar exchange rate while exports respond weakly, if at all; (e) strengthening of the dominant currency relative to non-dominant ones can negatively impact global trade; (f) optimal monetary policy targets deviations from the law of one price arising from dominant currency fluctuations, in addition to the inflation and output gap. Using data from Colombia we document strong support for the dominant currency paradigm.
Using recent advances in the classification of exchange rate regimes, this paper finds no support for the popular bipolar view that countries will tend over time to move to the polar extremes of free float or rigid peg. Rather, intermediate regimes have shown remarkable durability. The analysis suggests that as economies mature, the value of exchange rate flexibility rises. For countries at a relatively early stage of financial development and integration, fixed or relatively rigid regimes appear to offer some anti-inflation credibility gain without compromising growth objectives. As countries develop economically and institutionally, there appear to be considerable benefits to more flexible regimes. For developed countries that are not in a currency union, relatively flexible exchange rate regimes appear to offer higher growth without any cost in credibility.
We document that the U.S. dollar exchange rate drives global trade prices and volumes. Using a newly constructed data set of bilateral price and volume indices for more than 2,500 country pairs, we establish the following facts: 1) The dollar exchange rate quantitatively dominates the bilateral exchange rate in price pass-through and trade elasticity regressions. U.S. monetary policy induced dollar fluctuations have high pass-through into bilateral import prices. 2) Bilateral non-commodities terms of trade are essentially uncorrelated with bilateral exchange rates. 3) The strength of the U.S. dollar is a key predictor of rest-of-world aggregate trade volume and consumer/producer price inflation. A 1 percent U.S. dollar appreciation against all other currencies in the world predicts a 0.6–0.8 percent decline within a year in the volume of total trade between countries in the rest of the world, controlling for the global business cycle. 4) Using a novel Bayesian semiparametric hierarchical panel data model, we estimate that the importing country’s share of imports invoiced in dollars explains 15 percent of the variance of dollar pass-through/elasticity across country pairs. Our findings strongly support the dominant currency paradigm as opposed to the traditional Mundell-Fleming pricing paradigms.
China’s exchange rate regime has undergone gradual reform since the move away from a fixed exchange rate in 2005. The renminbi has become more flexible over time but is still carefully managed, and depth and liquidity in the onshore FX market is relatively low compared to other countries with de jure floating currencies. Allowing a greater role for market forces within the existing regime, and greater two-way flexibility of the exchange rate, are important steps to build on the progress already made. This should be complemented by further steps to develop the FX market, improve FX risk management, and modernize the monetary policy framework.
''In summary, the book is valuable as a textbook both at the advanced undergraduate level and at the graduate level. It is also very useful for the economist who wants to be brought up-to-date on theoretical and empirical research on exchange rate behaviour.'' ""Journal of International Economics""
Economists writing on flexible exchange rates in the 1960s foresaw neither the magnitude nor the persistence of the changes in real exchange rates that have occurred in the last fifteen years. Unexpectedly large movements in relative prices have lead to sharp changes in exports and imports, disrupting normal trading relations and causing shifts in employment and output. Many of the largest changes are not equilibrium adjustments to real disturbances but represent instead sustained departures from long-run equilibrium levels, with real exchange rates remaining "misaligned" for years at a time. Contributors to Misalignment of Exchange Rates address a series of questions about misalignment. Several papers investigate the causes of misalignment and the extent to which observed movements in real exchange rates can be attributed to misalignment. These studies are conducted both empirically, through the experiences of the United States, Great Britain, Japan, and the countries of the European Monetary System, and theoretically, through models of imperfect competition. Attention is then turned to the effects of misalignment, especially on employment and production, and to detailed estimates of the effects of changes in exchange rates on several industries, including the U.S. auto industry. In response to the contention that there is significant "hysteresis" in the adjustment of employment and production to changes in exchange rates, contributors also attempt to determine whether the effects of misalignment can be reversed once exchange rates return to earlier levels. Finally, the issue of how to avoid—or at least control—misalignment through macroeconomic policy is confronted.
This paper analyzes how the formation of Global Value Chains (GVCs) has affected the exchange rate elasticity of exports. Using a panel framework covering 46 countries over the period 1996-2012, we first find some suggestive evidence that the elasticity of real manufacturing exports to the Real Effective Exchange Rate (REER) has decreased over time. We then examine whether the formation of supply chains has affected this elasticity using different measures of GVC integration. Intuitively, as countries are more integrated in global production processes, a currency depreciation only improves competitiveness of a fraction of the value of final good exports. In line with this intuition, we find evidence that GVC participation reduces the REER elasticity of manufacturing exports by 22 percent, on average.
